Abstract
The invention discloses a device for performing simulation test on influence of medicament spraying in a lake on performance of heavy water. The device consists of two members, namely a spraying simulation device and a lake simulation test column; the spraying simulation device can control spraying flow, hydraulic pressure and spraying positions, and a spraying nozzle can be replaced to adapt to different spraying schemes; and the lake simulation test column can simulate overlying water of lakes with different water depths and the thickness of polluted substrates, and sample taps which are formed in intervals of 100mm can perform layering monitoring on the researched water body. The device can be used for simulation study on the influence of medicament spraying on the overlying water of lakes and substrates and the passivation effect in the lake bottom sediment passivation project, adjust the spraying intensity and positions according to actual requirements, and can perform layering monitoring on the water sample.
Description
Affiliated technical field
The present invention relates to a kind of medicament and spray the simulating test device on lake overlying water and substrate impact, for bottom mud in lake, pollute passivation engineering Chinese medicine and spray the modeling effort on the impact of lake overlying water and substrate and passivation effect.
Background technology
Study certain environment-friendly materials absorption property to pollutant in practical application engineering, conventionally adopt dosing, stir and evenly mix, the Static simulation test of standing observation.It is according to chemical feeding quantity, the temperature of setting and the definite time controlled, by the water pollution substrate concentration of different time points before measuring not dosing and after dosing, can calculate the engineering static simulation adsorbance of sorbing material under different condition.But this conventional static analog device can not be investigated the impact of engineering medicament spraying method on sorbing material adsorbance, and in the time of can not investigating generation water disturbance, in substrate, pollutant discharges the situation that affects on different layers overlying water, especially for the polluted bed mud in-situ passivation technology in treatment of internal phosphorus, this technology is at polluted bed mud surface coverage one deck, to have the flco of very strong adsorptive power, the pollutant that flco discharges adsorb bed mud under static condition in, in the case or while there is water disturbance, investigate the successively regularity of distribution that in bed mud, pollutant is released in overlying water very necessary, but, conventional static analog device can not meet the demands.
Summary of the invention
For existing conventional static analog device, cannot be applicable to study medicament completely and spray the impact on lake overlying water and substrate, the present invention proposes a kind of simulation test device, this device can be studied medicament and spray the impact of engineering on lake overlying water and substrate performance under static condition and disturbed conditions.
Main member of the present invention has two, and the one, spray analogue means, another is lake simulation test post.Sprayer apparatus is comprised of medicament barrel, O3-61/4-15 type submersible pump, glass rotameter, tensimeter, diverting valve, iron pipe, silica gel hose, PVC sleeve pipe and the nozzle that sets according to demand.The liquid that sprays of desired concn is housed in medicament barrel, by submersible pump, inject the pipeline being built by cast carbon steel, liquid enters after pipeline, by two pipeline flow dividings, article one, by diverting valve, controlled, directly return to medicament barrel, in order to regulate the flow of another pipeline, another connects silica gel hose, glass rotameter and tensimeter are set on this pipeline, coordinate diverting valve, can control and spray flow and hydraulic pressure, by silica gel hose, connect nozzle, can implement to spray, spraying position can regulate as required, by PVC sleeve pipe high scale, locate to realize, nozzle is also replaceable to adapt to the different schemes that sprays.Lake simulation test post is internal diameter 400mm, the PVC cylinder of high 2000mm, its sealed bottom, open topped, can overlap gland bonnet, can simulate aerobic and anaerobic condition, side-wall hole is drawn as sample tap by PVC tubule, adjacent samples oral pore heart septum 100mm, testing column bottommost is not established sample tap, and 11 sample taps are generally set from bottom to up, also can set up as required, monitoring by this simulation test post differing heights sample tap water sample, can realize the hierarchical monitor to water sample.
The invention has the beneficial effects as follows, can spray the modeling effort on the impact of lake overlying water and substrate and passivation effect for bottom mud in lake passivation engineering Chinese medicine, and can regulate according to actual needs and spray intensity and spray position, and can realize the hierarchical monitor to water sample.
